Abstract
A variable diameter pulley assembly for use with a power transmission belt and adapted to be connected to a shaft comprising opposed sets of axial and radial movable generally triangular or trapezoidal-shaped flange members, the sides of opposed sets being in substantial engagement to provide at all pulley diameters a generally cylindrical and continuous surface for belt engagement. A pair of axially movable hubs supports the flange members, and each hub has guides for guiding the flange members in their axial and radial movements. A central cam member with conical cam surfaces may be provided which cooperates with cam follower surfaces of the flange members whereby axial movement of the flange members causes radial movement thereof.
